the 29 known Mersenne primes are given below in terms of p where
2^p-1 was prime, and  (2^(p-1)*(2^p-1) was perfect:

	2	3	5	7	13	17	19	31
	61	89	107	127	521	607	1279	2203
	2281	3217	4253	4423	9689	9941	11213	19937
	21701	23209	44497	86243	132049

chongo /\../\  (2^23209-1 is prime!)

p.s. happy prime hunting  :-)
